text: HF/SbF is a highly corrosive substance that reacts violently with water. Heating it is dangerous as well, as it decomposes into toxic hydrogen fluoride gas. With superacids that are fuming and toxic, proper personal protective equipment should be used. In addition to the obligatory gloves and goggles, the use of a face shield and respirator are also required. Regular lab gloves are not recommended, as this acid can react with the gloves.  Safety gear must be worn at all times when handling or going anywhere near this corrosive substance, as fluoroantimonic acid can protonate every compound in the human body.
